| | |
| | * cooking/reheating with electric appliances can be a cheap and easy way to **use up "extra" power**. ie, cooking with electric //when you have it to spare// |
| | * but depending on electric cooking/reheating 100% requires [[electrical:12v:intro|power systems]] too expensive, physically large, and complex for many offgrid 'dwellers.((if you //know// you will have [[electrical:shore_power|shore power]] then go for it)) |

| Cooking and heating water with electricity off-grid is usually impractical but there are exceptions. In some cases the relatively large power loads can be used without affecting [[electrical:12v:intro|house battery]]((or starter battery)) [[electrical:depth_of_discharge|state of charge]]: | Cooking and heating water with electricity off-grid is usually impractical but there are exceptions.
